BALENCIAGA GINZA
Adopting construction-project scaffolding and mesh materials as its design themes, this special-order scaffolding frame system is accompanied by a metallic facade utilizing 3D-formed expanded aluminum. In addition to the facade, SFL handled construction and installation work for signage, lighting, stainless-steel sashes, and the sash-frame stairwells surrounded by tenant staircases.
INBLOOM
Based on a "crystallized architecture" concept, SFL participated in this project through its aluminum-panel facade using triangle forms as its basic motif. The complex, polyhedral arrangement comprises various elements including flat and three-dimensional aluminum panels, flower-pattern openings and more. SFL handled everything from design through to fabrication and installation of the facade using building information modeling (BIM) technology.
New Nakano City Hall Building
We installed 48 solar panels over a roughly one-and-a-half month period on the south-facing facade. Together, these serve as an important element in the new building's goal of realizing improved energy savings.
Morinaga Shibaura Building
We were in charge of the large louver-like grid elements on the building's exterior. The design required extremely high construction and installation precision, which we achieved through thoroughgoing quality management.

Special-glass Curtain Wall Installation
In accordance with the intended design look, we utilize various types of glass from manufacturers both in Japan and abroad, and harness a wide range of installation and fitting methods, including dot point glazing (DPG) which provides support at specific points using metal fittings.

Technology

DPG
Dot point glazing, or DPG, installation uses glass supports. It entails machining of countersinks into the four corners of tempered glass panels and fixing of the panels into place using flat head bolts. This approach provides the unique advantage of excellent adaptability to building-structure deviations. It also results in a flat exterior finish for the glass panels and facilitates the creation of highly transparent glass facades.
MPG
Metal point glazing, or MPG, is the affixing of glass panels at edge and corner joining sections by sandwiching them between metal fittings on the inside and outside. It uses fewer support fittings compared with sash-based supports which pass through the glass, resulting in clear and almost perfectly smooth glass facades.
SSG
Structural sealant glazing (SSG) is a system of adhesive-based glass panel support using structural sealants. This allows for the realization of frameless glass curtain walls.
Two-Dimensional Bending
Two-dimensional glass bending encompasses various types of bending processes suited to the intended form, including both hot and cold bending. All approaches entail bending of plate glass panels, and these range from relatively simple radial bending to complex S-curve bending aimed at actualizing a wide range of different dimensions.
Three-Dimensional Bending
Three-dimensional bending primarily uses hot bending processes and enables the creation of complex forms. Three-dimensional measurement devices are utilized, and 3D models are harnessed to efficiently manage permissible error. These enable elegant and precise creation of unique facade designs.
Ceramic Printing
Ceramic printing is applied to achieve more sophisticated glass designs. Ceramic ink is applied to one side of float glass and baked on using a heat treatment, which strengthens the glass. By typically applying printing on the interior side of the glass, and with proper maintenance, it can maintain its aesthetic appeal over an extended period.
